Answer:
The correct answer is 8
Step-by-step explanation:
yeah I checked the answer is 8 the person who said it the chat is correct.
Answer:
30
Step-by-step explanation:
Step 1: Find the area of the whole figure
The whole figure is a rectangle with a width of 4cm and a length of 12cm
The area of a rectangle can simply be calculated by multiplying the width by the length
So area = 4 * 12 which = 48
So the area of the whole figure is 48cm²
Step 2: Find the area of the non shaded area
The non shaded area forms a triangle with a base length of 9cm and a height of 4cm
The area of a triangle can be calculated using this formula
where b = base length and h = height
That being said we plug in the values into the formula
Hence the area of the non shaded region is 18cm²
Final step: Our last step is to subtract the area of the non shaded region by the area of the whole figure
so the answer = 48 - 18 which equals 30
Hence the area of the shaded region is 30 square centimeters.
Given:
A standard 6-sided dice is rolled.
If you roll an even number you get two points.
If you roll an odd number you lose one point.
To find:
The expected number of points per roll?
Solution:
If a dice is rolled, then the possible outcomes are 1, 2, 3, 4, 5, 6.
Odd values are 1, 3, 5 and the even values are 2, 4, 6.
The probability of getting an odd number is:
The probability of getting an even number is:
The expected number of points per roll is:
Therefore, the expected number of points per roll is 0.5.
